I cannot add existing Local IIS Web Site.

When I click the [Local IIS] at Solution->Add->Existing Web Site,

I got the error,

You must be a member of the Administrators group on the local computer to access the IIS metabase. Therefore, you cannot create or open a local IIS Web site. If you have Read, Write, and Modify permissions for the folder where the files are located, you can create a file system Web site that points to the folder in order to edit the files.

I'm running the VS2005 with Administrator account. So I don't think I'm not a member of the Administrators group.

What should I do?

Thanks advance
